Saints safety and special teams maven Erik Harris underwent ACL surgery today and will be out for the remainder of the year, according to Ian Rapoport of NFL.com (Twitterlinks). Devastatingly, Harris suffered the torn ACL — and meniscus — while intercepting Drew Brees in practice on Monday.

Harris, 26, was in the midst of his first NFL season, as he spent 2013-2015 in the CFL playing for the Hamilton Tiger-Cats. The California University (Pa.) alum signed a futures deal with New Orleans earlier this year, and ended up making the club’s initial roster. Through four games, Harris had only played two defensive snaps, but managed to see action on 82.5% of the Saints’ special teams snaps.

With Harris sidelined, Rapoport tossed out fellow safety Alden Darby, who was with the Saints during training camp, as a possible option to be signed in the coming days. Darby was waived/injured by New Orleans in August, and went on to spend a few days on the Colts’ roster.
